Bello, Patrice published the artcileUpping fragrance intensity via cyclodextrins: expert noses and headspace/SPME-GC confirm effects, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is cosmetics cyclodextrin perfume skin fragrance volatile compound.
The aim of the study is efficacy and potential benefits of cyclodextrins in delivering fragrances with and without CDs were compared using headspace/solid-phase microextraction gas chromatog. All measurements and assessments were carried out on the volar forearms(s) of one Caucasian subject in a controlled environment: 25 ± 1°C and 30% ± 5% relative humidity. GC test protocol: The GC test protocol included: 1) washing the subject′s forearm three times with ethanol and allowing it to air-dry: 2) spraying 200 mg of a test EdT three times and allowing it to air-dry for 2 min; 3) a 20-min stabilization phase: 4) a 20-min extraction phase; 5) a 2-min desorption phase; and 6) CO-MS anal. To trap gas, a glass bell jar (105 cm3) was used, along with a syringe incorporating an SPME fiber in polydimethylsiloxane (PDMS), to absorb volatile compounds Olfactory test: The olfactory test procedure involved washing both of the subject′s forearms three times with ethanol and allowing them to air-dry, then spraying -200 mg of a test EdT three times and allowing it to air-dry for 2 min. Twenty perfume experts then smelled the two forearms to make assessments. Measurements and assessments were performed every- three hours to determine the perfume evolution on skin. Results from the headspace/SPME-GC anal. indicated that initially (T0), the fragrance samples with and without CD had the same perfume intensity. Three hours later, however (T+3 h), the CD-containing perfume was approx. 50% more intense than the perfume without CD.
